Abstract
A display device includes a light emitting unit, first and second capacitors, and first and second switches. The light emitting unit emits light according to a voltage level of a first node. A first terminal of the first capacitor is coupled to the first node, and a second terminal of the first capacitor is coupled to a second node. A first terminal of the second capacitor is coupled to the second node, and a second terminal of the first capacitor is coupled to the light emitting unit. A first terminal of the first switch is coupled to the first node, and a second terminal of the first switch is coupled to the light emitting unit. The second switch is configured to be turned on before the first switch is turned on, and a first terminal of the second switch is coupled to the first node.
